Sour Dubb X Topanga Canyon - 4.1th grw

Feb 19 - starting to fill in although still small for how many weeks. been cutting off all lower nodes every other day. watering a bit more although the pots seem quite heavy. still mottled yellow leaves on the one plant. added Rocket Fuel that contains potassium so maybe that will help correct but idk if that's the problem. monitors are Temp One/Humidity One
